Strength to weight wise there won't be much in them at all. The only area the Team will be stiffer in will be the brake feel. You could argue that the extra 100 or so grams extra weight on the team is pretty much just booster plate. This could make a little difference to the stiffness of the frame when pedaling, but whether it'd be a noticeable difference when compared to the Lite, that's definitely debatable. When you talk actual strength to weight, the light might just shade it, as it's lighter but not discernibly 'weaker', just not as stiff in certain characteristics. Personally I'd go for a Lite and then get a booster if the brake wasn't as stiff as I'd hoped. Lighter way and about the same price. Geometry though.... Personally I love sort 20" bikes, though with just 10mm between the short of each frame, the extra 10mm cockpit room would be welcomed by most people. But 10mm shouldn't have too much of a detremental effect on bunnyhops etc. A 1025 Lite would be a lot of people's choice just because the short is too short. Argh, decisions. All that said, for ME, if the short lite was a little too short, I'd accept the extra weight and get a 1015 Team, as the extra 100g ish over a long Lite would be glossed over by the extra flicky handling of the 10mm shorter Team.
