Well my HPSB has gotten a tad beefier with age and the move away from the potato chip era,but is still absolutely a must have for me.. The " ride x inches shorter than_ " actually helped me when getting a few boards from the SAME shaper.(as mentioned,talk to 'em) The dd/grovelers scaled nicely in relation to the "good wave " boards In length,width,thickness and yes,volume. That makes switching boards seamless and feels natural... Now when you switch from mid-lengths to Std shortboards to fish to hulls, to stubs, etc. more "relearning" will certainly come into play.
In the end it's a ll about what makes your special place tingle.
