Pretty tall then! I would say go for Stock, you are welcome to try out mine tmrw (if its working) I ride an Onza T-Rex (2005 model onwards I think) - great starters bike for trials, and wont cost the earth. However, Daz from Notts is about 6ft 5 and rides a Zona Zip mod. Another great starters bike. Check out www.tartybikes.co.uk for loads of full trials bikes. Hope this helps!
