Been meaning to give em a try. Before I do, seeking some input by folks with experience in their use.
1) How do they fly when compared to field tips?
2) How do did you practice with them? Seems like it's a one shot deal.
3. Do they fly consistently, one head to the next, or does each one have to be tuned?

Any other info tha may be useful?

All set with Spitfires for tomorrow, but my tinkering mode is kicking in

PS. Realize I have to modify my stirrup.
