Nice one, that should serve you well.

There is a recent thread HERE that mentions the popularity of the Tau 7. My Tau 7 was running hot when I bought it (536 fps with Hobby/Geco), it had a kick to it and was wasting gas at the muzzle so I adjusted down to 475 fps.

Some good information on the Tau 7 in THIS link.

Any problems, ask folk on here, there are plenty with experience of the Tau 7.
