I think I might try the Underworld. I really cut back my use of the River due to its touchiness and switched back to the Leopard, so I'm curious if the Underworld can bring back Swedish plastic into that spot for me
Tursas is a must buy.
Stag is dreamy, but only if it is noticeably more LSS than an Opto Saint. Perhaps I may even switch to a GL Saint, Opto Stag combo
