I could be bias though as I own a small tank and a Pasha and love them both equally. But purely based on look, I like the Pasha. Since you have the mid size tank already, I think the Pasha will give you a different look altogether. It's more sporty and casual (if this suits your lifestyle). Both are great choices though
Thanks for all the comments ladies!! I really appreciate I haven't purchased the watch yet. I will do it on Friday I hope. Keep the comments coming, I haven't decided yet.
