... I'm realizing I'm having a hard time making up my mind as to which I prefer. I know I prefer a no-wrap cue around 19 oz.
If you looking for wrapless cue for under $500, you really can't go wrong with a newer Meucci with his Pro 12.5mm, Ultimate Weapon 11.65mm or carbon fiber shaft. I have 4 of them, and all were purchased in the last 6-8 months. So many great deals and unique designs (some are super tacky, but I like many others) at the budget billiards/budget cues place. Prices for mine are: $360, $415, $650, $650...but they have a wide selection in the $300-$500 range.
...recently I've gone back and forth between 2 different cue manufacturers. [...] Ever switch back and forth?
Every couple of games I will switch cues at home...have over 30 ' known brand' cues.
Starting from ~$100 Players to +$1,200 Schons...it is a lot of fun if you have a home table. I love going back and forth from 11mm skinny LD cues w/ a laminated tip to a 13mm hard maple w/ Triangle...can play well with both and variety is the spice of life. My favorite brands personally are: Mezz, Meucci, Schon & McDermott...although I love my Joss, Lucasis, Vikings and Pechauer too.
However, if you playing mostly at pool halls, then definitely get what you like and stick to it. It would have saved me a lot of money if I knew what I wanted from the get go. It took me almost 3 years to know exactly what I like, because I play by myself unless someone is over.
Regardless of what cue you decide to choose, practice until you are proficient, and make sure you have a good stroke and solid fundamentals at the table. I can't emphasize this last statement enough.
