ICEMAN has had lots of good things to say about his 2300 ST and it seems like a good choice for the price. Its close to a 1.60 OS in power and would really do the trick. My Magnum never held tune and always deadsticked. It ran a lot like the Tower 46's that some people love and others like me hated. I know a lot of people talk about flying Big Boys with .91 FS or 2S but I would want a little more. I fly a 60 Size Ultra Stick with an OS 91 surpass and it is great but the added drag of a bigger wing and more weight may be too much for it. A 1.08 OS would be a good choice but is a lot more $$ than the ST.
