I just got it a few weeks ago ... got about 10 sessions on it so far .. all chest-head high+ ... board has been pretty amazing. Been riding a 6'4" MR Cali Twin and a 6'6" Pyzel Ghost this season ... the Moonstone is narrower than both at 20" - was apprehensive at first but have had no issues with the width so far. Still dialing in fins though - i've got the CI AMK's they worked pretty well up and going but felt like a little too much fin on smaller waves - today tried the Lovelace Piggyback keels and they were ok but didn't really light up the board. i have a set of the RFC Twinzer twins and they really lit up the board ... they have a really narrow base and a lot of rake .. but this past week we had 5 straight OH days of pumping surf and they didn't cut it not enough fin. Tried the Machado keels ... too stiff to my liking. So maybe the BMTs might be the call.
the regular swallow version i really like the cc keels capt fin used to make. Feels perfect for me. Another guy I know has been riding his with bmts and liking those also.

I’d be curious to hear a comparison between the feel of the BMTs vs the Pyzels.

I compared them in a shop when I bought the Pyzels- which I’m using in a twinzer. BMTs looked like too much fin for that set up.
They are definitely big. I thought about running them in my Aipa one day and stuck them in and took them back out. Just didnt look right, too much fin. I had picked them up thinking I would try them in my townsend, but then ended up selling the board.

On the Moonstone the late wing - baby swallow tail is really pulled in ... from Album it is suppose to give more hold on steep waves and a little easier on the backhand compared to the original swallow. I've noticed even with the long rail line standing back on the tail it redirects really easily. i tried the ENs ... on a couple of waves that were walled up and well OH they felt really good but otherwise felt like they had too much drag ... struggle to catch waves. Gonna put an order in for a set of BMTs. Fortunately there is a new company down here that so far has been able to get things down here in 2 weeks or less are a reasonable rate.

I'd be surprised if they help any catching the wave. They have more surface area, more raked, and more cant angle than the EN's fyi. They will probably feel a little more stable and faster down the line though.

For anyone with an asym, I highly recommend these fins. Really good balance of drive and pivot. I put them in everything from my DD to my step up.

Twin sets available too!

You're probably right but i should add that the ENs i have are really old ... stiff fiberglass .... they've always felt like they need a wave with some energy behind it. Running the AMKs in the Moonstone, in comparison, felt like they paddled faster, got into waves easier along with a better feel on bottom turns and cut-backs. The AMKs also have a different foil - especially on the leading edge I'm thinking/hoping the BMTs will have a similar feel with less overall area.

Any thoughts on how those paddle fins would go as a full quad set in a quad fish? I don't really seem to quite click with split keel templates so always looking for alternatives.

I'd be willing to bet they would go really good.

I've tried a few different hatchet fins in the past and in every case the base of the fin was cut short to make the hatchet. They felt really good through turns but because the base was cut short, they always felt like they lacked the ability to generate the speed I wanted out of the gate and down the line.

These are different because they retain the full length of the base but cut away a section of the trailing edge. It's essentially adding pivot to a drivey raked fin.

Thanks. Think I've felt similar loss of speed with the old Tomo/Krypt hatchet fins... at inopportune times.
Might give these burch a shot
