HT Mount Angles

[Troph]

First I'm not sure if the title reflects on what I'm trying to ask for. I have still yet to buy one of these but I still want to do some more homework and one thing i haven't been able to find is what the angle of the mounts are relative to each other. in other words what is the sought after angle between the seat post and the bottom tube. and i realize they can be fudged a bit...ok alot.

I'm not sure on everyone else, but I like to get the rear of the engine high enough so when you get the chain worn in, you can remove the chain tensioner and run the chain straight to the wheel and back without hitting any frame parts. Eliminating the chain tensioner will make it more reliable.
