ive got the XXracer the one before the APEX and its a good buggy but it doesnt have the kicks in the side rail of the APEX, (which i'd love to try). as for the xxracer great in the corner and very controllable good reactive buggy, but if its gusty and a dirty wind my legs are xtra swore from pushing myself back into the seat, the side rails aint very secure and i've the seat as low as it can go with extra padding to the side rails. but still prefer my mates T3. side railes on it are great, higher so i have changed the way i hold my handles on a short strop line.
had a baracuda before (which is still FOR SALE full stainless, very secure, comfortable and high side rails £450 ono) XXRACER is great if the side rails just had a little more height and the "kick in" for lockin in, which is now how the apex is.
for the money the T3 is a serious bit of kit, well balanced, very secure and great in the corners. would happily hold a bigger kite in a T3 and feel ALOT securer that the xx racer
