This has been a useful thread. Despite his best effort and flawed physics theories, LFC gave precisely zero sound reason not to try TSS. On the contrary, Dean and Pullit supplied reasoned, sound data and first hand accounts. I've now accumulated 4 boxes of 20g TSS #9 shells and 2 boxes of TSS #7 shells. Weather permitting, I'll try them out of Tinkerbell this weekend.
