How tall are you? I'm 6 foot 3 and mainly skate ledges, curbs, manny pads, but 8.38 with a 14.5WB and 32.5 length seems fucking insanely big.
About the same height when I did the conversions of cms to inch / foot measurements, but I skate more transition and have found that the wider stance is easier.
I used to ride the AH black eagle 8.125 x 32 with 14.25 wheelbase for almost 15 years as well as having lots of different sized setups, then in the last few, more so the 8.5 x 31.8 with 14.25 wheelbase but found it too short, so the 8.5 x 32.25 with 14.38 was more comfortable, but I think I am becoming more lazy too, so don't do as much on street or tech tricks as I used to, which was why I never wanted to go up from the black eagle because I could throw it around so easily.
A couple of others I know all ride the same bigger board size and can still do everything street tech, flip, etc and have no issues with size on the 14.5 wheelbase, so it is just something I guess we got used to because there were a lot more available.
