How about some dedicated long-lens-holder like this one: http://www.manfrotto.com/product/templates/templates.php3?sectionid=103&itemid=354

Hi,
I concur on the M*300/4 as a very nice hand-holdable long lens. I use it a lot at the races. My only gripe is that it's a heavy lens with no tripod collar, meaning I pretty much *have* to hand-hold. Puting that much unsupported weight on the camera's lens mount scares me a wee bit, and it does tend to be twitchy on light- and medium-duty tripods.
I once saw, but haven't been able to retrace, a V-shaped device that fits on top of a tripod. You can put a beanbag in the V, and rest a long lens on it apparently quite securely. I always thought it would be a very useful little thing when I had my A* 300/4.
