Been looking at the this conversion kit from DiveRightInScuba and it seemed to be a very well made piece of kit. Have noticed that there have been made posts made on using HOG 1st stages with what I believe to be adaptors and not conversion kits but I'd just like to confirm whether the conversion kits will add any noticeable potrusions. I'm going to use the pair on my sidemount kit so it'd be nice to have as little clutter as possible around my armpits.
