You can do ALL your training in a C152 if you want - but the TEST must be in a 'High Performance' type, which is defined as CSU + 120kt cruise TAS.
For my bit, did GFPT in C152, all my PPL in C172, then some time in PA28, then some more C172 for the CPL, then some PA28R for the navs et al, then PN68 for the MECIR, then 1st job in a C182, then some PAY3 for the turbine / pressurisation thing + some ICUS, then more C182, then some day work in a PA34, then the Aztec for ME IFR CHTR.
End result - wish I'd done it ALL in a twin. Horses for courses butch; make up your own mind, but be very clear on your AC type numbers and procedures when time comes for the CPL test. The C182 is very hard to beat for cost/benefit.
Have fun! Spend dollars! Make noise!
