The wheelbase on the 32" board is only 2.5" shorter than the wheelbase on the 36." They both will be pretty stable, especially if ur planning on putting 150mm trucks on it or if you get some 150 reverse kingpins it will be stable enough for going fast. I would get the bug tho, I've ridden both boards n the bug can do pretty much everything better that the sizzler can- pools, ditches, a little bit of street skating and it just feels better. The sizzler's fish tail is a really stupid idea since it takes away a lot of it's pop and feeels goofy when ur on the tail. Just buy the bug cause it will be almost perfect for flat ground stuff.
