I've been shooting the G5 Tekan the past couple of years. It has the same deployment system, but has one less blade. I have nothing bad to say about the Tekans. The blades are scary sharp. The entrance holes are as large as the exit, and they group with my field points. Of the 3 deer i've killed with them, none had left my sight.
I'll likely shoot the T3 this year. Everything i've ever seen of G5 has been top notch. My guess is the T3 will be too.
