I got out on a very old (2017) Grant Taylor 8.5 full today to experiment with a longer wheelbase (14.6 ish) and overall length (like 32 and a half with a worn ass tail).
I slapped my 5ply risers, aces, and conical fulls on that old piece of shit and had the best session I've ever had at a nearby concrete park. It changed my entire view on wheelbase, as I was convinced my lil ass needed a short wheelbase to do certain tricks. Ordered the 8.75 eagle from the local, no more short wheelbase for me!
