GhiniCare to share what you do and dont like about the Beast 14s both in as out bounds?
In bounds, I don't like anything about any tech binding. Whether it be a beast or anything else, they still lack elasticity and forward pressure and if you ski hard through chunder or bumps, you are very likely to have a heel release. The only time I ski mine in bounds is when we decide to take some laps after touring. I also don't care at all how heavy my bindings are at a resort.
Out of bounds I like Beast 14's a lot. I lock my toes out when I ski, so the 16 toe doesn't really do anything for me. The Beast heel definitely a bit heavier than the Radical, but it's lack of twisting means it won't break on you while climbing. The only downfall really is the lack of a flat walk mode, but nothing I do on a regular basis in Utah has a very flat approach, so it doesn't bother me much. They are also expensive af though. So if you are paying retail for a Beast or a Radical, I would go radical.
SI&I is dope, but expensive. I also wouldn't want to ski the boots that I had modded in bounds everyday so that would add another pair of boots to the mix, adding to the cost. If the Pinnacle boot doesn't explode this year and when the new tech Langes come out next year and accept alpine soles like the XT, the SI&I will be a more viable option imo.
If you are considering a tech binding for in bounds use, I would look at a Kingpin before a Beast. The heel on the Kingpin is a trade off. It's a bit more confidence inspiring due to it being an alpine style heel, but it is more annoying when touring. I personally would rather deal with some ice on my bindings when touring than release in a mogul field though, especially given the op's ratio of touring to in bounds use.
But if you are only going to have one pair of skis for touring and resort riding, Trekkers with an FKS would be my choice.
