..........should i stick with sand wedge or use the lob wedge any advice and tips would be very welcome ,............
I take it from the wording of your post that you already have both so there's no money to be saved - but if you have spare money it really is worth having a lesson from the Pro on playing your bunkers with your clubs.
I also assume your SW has about 14 degrees of bounce on the sole, and the lob wedge doesn't (it might but it's more common off the shelf at 8)
So the real issue becomes when to favour using one over the other; if at all.
Lots of soft dry fine sand - SW
Heavy, wet, coarse, thin layer over compacted base - LW
Basically what the sole of the SW is designed to help you with in the first type of bunker doesn't really help with the latter - in the 'old days' if you were in a green side bunker that was hard and compacted the clever choice was the PW over the SW for this reason.
Finally, if you have both then why don't you just spend some time in a bunker with them and find out what works for you. The loft really isn't the relevant difference.
