Titan has the same 15* limb angle as the 17" DAS/Dalaa.Just to add to the confusion, I've read that the limb pocket angle of their 17" riser is the equivalent of a 21" riser to everyone else. So, if you stick to the losing 1 lb/inch per 1 inch of riser increase, a 30lb limb on a TT would be 30 lbs on a 21" riser of another maker, or 28 lbs on a 23" riser, not the 24 lbs you'd expect.
