As we older we need scopes more and more to take our quarry more efficiently and therefore more humanely. I figure the better I can see exactly that hair I am aiming at the less chance of muffing a shot and wounding my quarry. I prefer a low powered rifle scope with a fair size lens but many perfer the Lumizone and Varizone Excal scopes. Peeps are rarely used because they are less precise but some still use them.
Aluminum and carbon both have fans. Aluminum are more noisey but carry more clout. Few people for unknown reasons use feathers and I am growing to like them for crossbows.
As far as broadheads go for short compact heads. Mechanicals are getting better as years go on give the option of a wider cut. I still like the Montec and Striker but if I have time to get out deer hunting this year I might try a couple of mechanicals.
The change will come when those jackasses get too old to pull back their beloved compounds and just plain smarten up. They cannot stop the tide of change!
