Johnny,
i bought an 150 NP golf bag from a local retailer here in WA. First use, day trip with two boards, 2 kites, bar and harness) the handle tore on one side of bag. Took it back and they wouldn't replace. Instead of replacing they took to get reinforcing on the handles. Smiled at me and said that they had provided feedback to NP.

Second trip was 2 week international trip. On last day packing to come home zip failed. Only took it in today to upholstery place. He said zip was poor quality, especially for a long zip that goes around corners. Getting it replaced for $50 plus some more reinforcing on the weak points. Obviously I don't recommend the NP Golf Wheeled.
On on the other hand, I have a flying objects 140cm wheeled that is the bomb. Used it for 5-6 trips. 4 domestic and two international. My partner uses it now cause my light wind board is a 150. She's also done two trips with it. Rock solid construction, thick padding, bulletproof zip. Highly recommend.
I emailed Flying objects only just last week to see if they'd do a 150 (cause the NP needed repairs) but sadly they couldn't do it. Not enough demand for that size.
All up mate, spend the money, make sure the reinforcing is in the right places that padding is thick enough and zip looks solid.
Disclaimer: I have no affiliation with Flying Oblects and am not bagging all NP products. I have other NP items that are good quality, just the golf bag is/was pretty poor.
Simon.
