I would suggest you give Rosemarket Golf Club a try. Grass strip which is basically East / West and very popular with the C42 guys. I have landed my Taylorcraft there and would be Ok for the usual spam can brigade. PPR required on 01437-890281. No ATC so you need to over fly the strip at 800ft so the golfers get out of the way, plus you need to have a good look at the strip as you land between a gap in the hedge!
Strip obviously weather dependent and you park by the cars! Warm welcome assured plus usual golf club faire of bacon sarnies etc.
Located between Haverfordwest ( Who I suggest you talk to on approach ) and Milford Haven (N51'44.50 W004'5792) so just as far West as you can get for this type of strip and certainly a first for most! You could check out taking your clubs if you are into Golf!
