For cheap and light shooting, i use 1632 tapered with .5 grams 6mm BB's ammo .. the lenght is 4inch plus 2 inch tapered.. it can shoot 250fps to 270fps.
2040 tube: i use it with no frame setup, 15 inch lenght and 8mm ball bearing..great for plinking..
1745 tube: i use it for my ergonomic dancing dankung, loop band setup or tapered setup with 10mm ball bearing great for hunting bird and dart fishing..
hello admin, could you make ergonomic TTF. no tie flat band.. just like your ERGONOMIC OTT.. Thanks
