I second Steelforce.
As with all things in life it's what you did with it at the right time and moment.
The best things in life are not always insight as we tend for things at grasp.
I've read up on Silver Flames as they seem to be no doubt a superior made product. What German product isn't? Honestly was there ever a better made car for price then the VW Beetle?
Testing by someone here in th past of shooting them at (not into) block walls I beleive and not bending the head. So craftsmenship and quality are there.
But with Trad equipment I feel there a over kill and simply not worth the money.
With a wheely bow at 275fps you would probably pass thru both hind quarters including the bones of an elf and stick into a tree 10yards beyond, walk over pull it out and put back in ya quiver for the next one, but at 160 to 180 fps I don't think so.
There's a point where enough is enough and since only lQQking now it's better IMO to try other blades be it the stinger, or Zephr as you mentioned and see how they work keeping in mind the you could always try others.
Let us know what you choose and pictures of results as this is an exciting time for you for sure.
