One planner or more than one planner/organiser?

For a few years now I have been an advocate of the thought that 'You have one life, therefore you should only have one planner'

For several years I used an A5 at my desk and carried around a Filofax Personal size, occasionally an A6 or Pocket size depending on the phase I was going through. Whatever the size though, there was duplication. A diary insert in the A5 and another in what ever I was carrying around at the time. In general it worked, but occasionally there was a hiccup when something didn't get written in to either planner. 

This practice ended with the review of the compact Filofax Heritage that opened up new possibilities for me. I was able to carry the A5 size where ever I intending to go, leaving behind some of the A5 sections at home in another larger ring A5. Just keeping the essentials in a compact A5. This has been working well for me now for more than 5 years, possibly longer. 

That said, I'm about to break my own rule again! Travel, or more precisely air travel, something I've not done in recent years. I prefer to travel in Europe by train when I can. 

Budget airlines and some of the main carriers these days are quite restrictive on their baggage limits. I have a couple of trips coming up in the next few months, one a very quick two night stay in UK the other a couple of weeks in two European countries for a holiday we intended to take in 2020... and we all know why that didn't happen! 

In essence I'm looking to cut down my baggage to just a carry on bag for the short UK visit and a small light bag and case for the longer trip. I'm looking at everything I need for each trip. My 'packing list' has expanded over the years, it was therefore time to examine everything on the list and ask the question: 'Did you use this during the last 2-3 trips?' if not then it gets dropped. 

Naturally my organiser has come under examination. Yes I do use it whilst I'm away, life continues! But do I need something as big as an A5? 

I've been getting on well with my Pocket Kensington. Mainly as a notebook with a year planner. I decided to expand on its planning capability by adding a Month on Two Page diary insert and add in up coming appointments to it for the next few months to see how workable/useful it was. 

It is certainly a winner in terms of compact and light weight. When I'm travelling I like to be able to jot down things as I think of them. Also have a written record of booking numbers etc. The Pocket Kensington will be more than ample for these tasks. 

I was also considering using a Compact Personal size Filofax as an alternative. However, I will see how well I get on with the Pocket over the next week or two before trying that out.
