Genuine enquiry aimed at folks who have been in the same situation as me...what is the big deal with changing to sidemount diving from backmount doubles? what makes it worth the time, effort and money to learn and equip this skill? I am a cave and trimix diver. For the vast majority of cave dives that I would consider, backmount is fine. I can see that it might be easier to avoid stirring silt with sidemount - (pretty important) but then my chest is clear and this can be useful laying line etc. I have dived with sidemount buddies and apart from the longer time to gear up, there often seems to be a problem, usually some bit of bungee is too long or something and this causes trouble. So with all that commitment to diving a new system, what makes it worthwhile? Personally, I am more interested in the dive I'm doing than the gear I wear. I would rather spend my money on getting to a good dive site than on more training, bcd, 1st stages, hoses etc...there seem to be whole facebook pages dedicated to making and buying new harness rings! So somehow it really must be worth it, just interested to know what that is (apart from physical ailment side which I get). Many thanks
