My knowledge about this is mostly theoretical, but from what I understand rake angle in itself doesn't affect handling that much? What affects handling is primarily the trail number (which is of course a product of rake angle). In the "Tony Foale test" (https://tonyfoale.com/Articles/RakeEx/RakeEx.htm) they experimented with even using even 0 degree rake angle and found it handled pretty normally as long as the trail was kept the same.
..just saying that if the decreased rake angle results in less trail (and thereby twitchy/dangerous handling), then a smaller offset in the triple would pull the trail in the opposite direction. Could be like jag767 says it's way too small difference to compensate for the result of the decreased angle though.
Measuring rake angle with the current setup sounds like it'd be a good idea to put numbers on the change? (good luck getting the wife to do that
)
Does the forward lean have other implications than rake/trail? Would weight distribution change and affect handling?
