RE: I need your Opinion, Please.
For strictly fieldpoints, any bag target will do you right and much easier to remove arrows. I cant remember the name of the one I had but it was a cheapo cabelas bag target. It lived outside in the weather for years and finally tore away fromits frame holder. ...it still stopped arrows tho. I'll be looking at the suggested Morrel bag if I start shooting 50+ arrows a day.
For cheap, Im actually impressed with the Walmart version 4x4 for $27. It has two sides for fieldpoints and two sides for broadheads. Ive shot it about 200 times and its still alive n stopping arrowswithout the wrap/blazers making contact.
