Looks good, nice job and very satisfying I bet.
I used to do a bit of target archery a few years ago, and if I remember rightly you need a bow with about 40lbs pull to shoot a target at 100 yards with any consistency.
The arrow length is different and depends on your reach, with the bow held at arms length the draw is to your chin, the arrow needs to be 1 to 1.5 inches longer than that for safety reasons.
Lower poundage bows are good for shorter distances, and indoor shooting during winter months is usually done at 20 yards.
I'm not sure how i'd deal with being on the tele but i reckon I could go for it as long as I could be myself and they didn't try to use me to sell pocket knives and survival tat
With all the "celebrity" nonsense on the telly these days (I moved house 3 months ago and have yet to connect the aerial but do watch the odd thing on iplayer) there would certainly be a gap in the market but I fear that subtitles or a translator might be needed to break into the US market!
