I think either one is far better than any ST. I just took the first trip with the Coopers and I like them a LOT... very very stable. They aren't all steel - a magnet won't stick to the sides. Oh well, I'm not worried about that! A friend had 4+ year old FS TF HTs on his 5er and a month ago, he almost rolled it with his 4 seat Ranger on his first trip with a new toy tote attached to the 5er. The trailer was sliding across the road and tipped up on both sides til the front of the 5er crushed his bed down on both sides. The 5er came down so hard, the frame bent (completely buckling the I beam and smashing the spring hangers) over the axles, cracking the 5er sides (it's totaled) and all four springs are reverse arched now. The tires look fine except for some rubber scuffed off the tread. STs won't even last 4 years in these parts, let alone take that kind of punishment. FS TF is definitely a good choice. Craig
