Notice I keep saying "IMHO".

That translates as "InMy Humble OPINION".

In other words, what I like and prefer. When asked an opinion by the thread starter I gave it.

Daltrey now has to decide what is best for him/her (sorry, can't tell from the name). We can only give the advantages that we see and we value as individuals.

Round, oval and rectangular all have trade-offs--disadvantages and advantages. Daltrey must decide which are the most important in the Daltrey household.

Me, I prefer rectanular, oval and round, in that order. My reasons are based solely on my personal preferences for how I and my family use our pool. That's how it has to work for every pool owner. Personal preference.

I keep saying the best pool is the pool YOU love to use, that works best for you and your family. The worst pool is one you cannot use (having no pool falls into that category).
