I really like my 29er HT But I'm 6ft n 185 Lbs and I'm more into faster open places and long trails.
I'm also a rookie and the very few technical trails I have took my 29er on were fun and they whipped me good.

The very tight turns I have been on IMO would have been much faster and simpler on smaller wheels yes BUT my engines
are not up to speed yet so the 29" wheels give me an edge..

If I wanted smaller for tighter places I'd go to 27.5"......
