Therefore, if only insignificant effort and expense is required, there's no reason to not use the higher voltage. You may gain something. But even if you don't, it hasn't cost much either. IMO, a much better gamble than buying a lottery ticket.
If a significant effort or expense is necessary to utilize the higher voltage, then don't do it unless you're sure a problem exists.
