Hi system.
Id hold on b4 plumping for the S -rex's. Check with the Essex crew and see if you could try out T and S's--- I know peeps there have both types at one of their gym sessions.
Ive been bocking for a fair while and have just changed for T rex's to S rex type X ( I actually won them in a comp so didnt cost me anything
).
Im 12 stone and only after 9-10 months was I regularly 'bottoming out' my T's and only then when my techique was spot on. With the S's, whilst I love them. Ill point out some observations. 1st cos of the stiffer springs, if you are nor spot on with your style and dont get all your weight down , you get no bounce but do get a very definite jarring in the back. S rex frames and components are more solidly built than T's --cos of heavier weight of user and bigger stresses. This in turn means that I dont think you can simply buy an upgrade from t to s at the moment. Also I really notice the extra weight ( S rex about a 1Kg heavier than T's) for a lighter person this would be even more so.
On my original poweriSer stilts when my 1st lot of springs gave out I replaced with a heavier weight --but found I simpl could not compress them . The were like iron bars.
I really wouldnt want you to be in that position. I suspect you are really serious and could get darn good v quickly , so you need to get the right kit. If you lived closer Id gladly let you borrow my T's for a week or so.
Again if you wanna chat on msn im bmthbloke@glassisland.wanadoo.co.uk I think
