Its no rocket science to state that the WG is heavier than the Ti
The RM10 Ti is very light but the WG isnt heavy as well as you might think
I would suggest you try and feel both if you could
I had the RG before then got the 004 in Ti and now i have the 10 in WG all of which are extremly comfortable and considerably light where as the Ti is feather light
Try them on and have a sense of what you'll get or feel
