Sevr just released a new head today--a hybrid of the 1.5. I just tested it and it got the highest score of any head to date (over 300 heads). Check it out.
Killed 2 with the Sevr 1.5 last year. Blood trails had more to be desired but both crashed making easy recoveries. 1 ran 30 yards and fell over. The other made it round 100 and across a creek. I hit her really far back as she wheeled away and was quartered away ti start. Both were pass thrus. Pin point accuracy. Blades opened and locked correctly. Need to replace blades but head is just fine
