I guess I play what you would call woodsball, but in the desert. That is exactly the kind of marker I use. Spyder Victor. Just with a 12" barrel. I've used it for years. Very reliable. I've never played speedball because like you said, cost can be a factor. I can't fathom shooting 4 bags in 1 round, let alone shooting all day. Very cool video. Keep on keeping on!
I like woodsball and/or scenario games. At my age (68) I do not have the physical prowess to play speedball effectively. I like the less intense play of woodsball, though there are times it does get crazy. And I do use an electronic marker, an Etha 3 or my backup an Empire Mini. Don't play on a field that allows ramping in woodsball.
I've used a electronic gun before never liked. it stayed with mech and my og 98 custom with a stock and flatline berral but thinking on getting that saber hk one day for woodball fun
