Dear oh dear...... I once had a GU Typhoon 20" and i found that this had a disadvantage. I found it really hard to sidehop, it felt really weird and cramped when i did then. Whereas on a bike with a low bb (06 Python) I got my sidehops back to normal and found then much more easier. This doesnt mean to say that High bb bikes arent as good its just my opinion. Damon watson and Matt Arkwright both ride GU 26"s and their amazing on then. Where do I start.... Saddless bikes are much better in my opinion. That is if your a 26" or 20" rider. The last thing you want when your trying to ride is a seat, It gets n the way and When you "Tuk" on the bike it is often caught on your leg etc......... Not to say i wouldnt have a seat if i was riding a 24". So I would advice to have no seat on your bike if you ride 20" or 26"
